Objective: Patients with traumatic acute subdural hematoma (ASDH) often require surgical treatment. Among patients who primarily underwent craniotomy for the removal of hematoma, some consequently developed aggressive intracranial hypertension and brain edema, and required secondary decompressive craniectomy (DC). To avoid reoperation, we investigated factors which predict the requirement of DC by comparing groups of ASDH patients who did and did not require DC after craniotomy. Methods: The 129 patients with ASDH who underwent craniotomy from September 2007 to September 2017 were reviewed...

BACKGROUND: Ventriculostomy-associated cerebrospinal fluid infection (VAI) is a major complication limiting the use of an external ventricular drain (EVD) in intraventricular hemorrhage (IVH). Risk factors of VAI are still under wide discussion. METHODS: We performed a retrospective review of 84 IVH patients who underwent EVD at our center between January 2012 and January 2017. Preoperative clinical parameters, surgeon status, number of catheters and catheter-days, subgaleal tunneling distance, frequency of urokinase flush, and prophylactic antibiotics were compared between the infective and non-infective groups...

Aneurysmal subarachnoid hemorrhage (SAH) is a sub-type of hemorrhagic stroke associated with the highest rates of mortality and long-term neurological disabilities. Despite the improvement in the management of SAH patients and the reduction in case fatality in the last decades, disability and mortality remain high in this population. Brain injury can occur immediately and in the first days after SAH. This early brain injury can be due to physical effects on the brain such as increased intracranial pressure, herniations, intracerebral, intraventricular hemorrhage, and hydrocephalus...

RATIONALE: Intracranial medulloepitheliomas are extremely rare and highly malignant. Intraventricular medulloepitheliomas are even rarely reported, and little is known about the clinical features. PATIENT CONCERNS: In this article, we report two cases of intracranial medulloepitheliomas. In the first patient, a one-month old boy, the tumor was located in in right lateral ventricle, which was the first report of such location of this disease; in the second patient, an eleven-month old girl, the tumor was in right cerebellopontine angle...

BACKGROUND/AIMS: Obesity is increasingly becoming a major public health problem worldwide. Peripheral LKB1 inhibits white fat generation, but the effect of central LKB1 on diet-induced obesity (DIO) is unknown. Therefore, we examined whether LKB1 over-expression in the hypothalamus can inhibit the development of obesity. METHODS: Adult male Sprague-Dawley rats were anesthetized and placed in a stereotaxic apparatus. LKB1-AAV-EGFP (2.0 × 108 or 2.0 × 1010 vector genomes) or Control-AAV-EGFP (2...

BACKGROUND: The ICH Score has become the standard for risk-stratification of 30-d mortality in patients with intracerebral hemorrhage (ICH), but treatment has evolved over the last 17 yr since its inception. We sought to determine if the ICH Score remains an accurate predictor of 30-d mortality in these high acuity patients. OBJECTIVE: To determine the role the ICH Score has on mortality in current treatment of patients. METHODS: A retrospective review of 554 patients treated for acute, spontaneous ICH at 2 large academic institutions between 2010 and 2014 was carried out...

Hematoma expansion (HE) is an independent predictor of poor outcome and secondary neurological deterioration in intracerebral hemorrhage (ICH) and is associated with high morbidity and mortality. Noncontrast computed tomography (NCCT) may identify the sites of active extravasation. Therefore, we have attempted to (1) devise a reliable and easy-to-use prediction score to predict the risk of HE in ICH and (2) validate the accuracy of this grading system and perform an independent analysis of HE predictors. We included patients in whom an intracerebral hemorrhage (ICH) occurred in the basal ganglia between Jan...

The Zika virus (ZIKV) is a flavivirus currently endemic in North, Central, and South America. It is now established that the ZIKV can cause microcephaly and additional brain abnormalities. However, the mechanism underlying the pathogenesis of ZIKV in the developing brain remains unclear. Intracerebral surgical methods are frequently used in neuroscience research to address questions about both normal and abnormal brain development and brain function. This protocol utilizes classical surgical techniques and describes methods that allow one to model ZIKV-associated human neurological disease in the mouse nervous system...

BACKGROUND: It is unclear whether a neonatal or a fetal growth standard is a better predictor of adverse in-hospital newborn outcomes. OBJECTIVE: We aimed to evaluate and compare the power of birth weight for gestational age to predict adverse neonatal outcomes using neonatal and fetal growth charts. Gestational age specific birth weight was examined either as a centile score or as a binary indicator for birth weight below the 10th centile (small for gestational age) using three fetal growth charts (National Institute of Child Health and Human Development, World Health Organization, and Intergrowth-21st ) and one neonatal sex-specific birth weight chart...

PURPOSE: Whether pathologic alterations of right ventricle (RV) in chronic obstructive pulmonary disease (COPD) affect intra- and interventricular dyssynchrony due to changes in mechanical activation of the septum and RV is unclear. The aim of this study was to determine mechanical activation and its changes after pulmonary rehabilitation program (PRP) with speckle tracking echocardiography (STE) in COPD patients. METHODS: After the exclusion of 15 patients due to poor echogenicity and 5 patients not tolerating PRP out of 69 consecutive COPD patients undergoing PRP, the remaining 49 patients and 41 healthy subjects were enrolled...

Antenatal corticosteroids remain one of the crucial interventions in those at risk for imminent preterm birth. Therapeutic benefits include reducing major complications of prematurity such as respiratory distress syndrome, intraventricular hemorrhage, and necrotizing enterocolitis, as well as an overall decrease in neonatal deaths. Optimal reductions in neonatal morbidity and mortality require a thoughtful review of the timing of administration. In addition, a thorough understanding is required of which patients maximally benefit from this intervention in the management and counseling of those at risk for preterm birth...

BACKGROUND: Germinal matrix-intraventricular hemorrhage (GMH-IVH) is a common form of intracranial hemorrhage occurring in preterm neonates that may affect normal brain development. Although the primary lesion is easily identified on MRI by the presence of blood products, its exact extent may not be recognizable with conventional sequences. Quantitative susceptibility mapping (QSM) quantify the spatial distribution of magnetic susceptibility within biological tissues, including blood degradation products...

Cardiac atrophy is the most common complication of prolonged application of the left ventricle assist device in patients with advanced heart failure. Our aim was to evaluate the course of unloading-induced cardiac atrophy in rats with failing hearts, and to examine if increased isovolumic loading obtained by intraventricular implantation of an especially designed spring expander would attenuate this process. Heterotopic abdominal heart transplantation (HTx ) was used as a rat model of heart unloading. Heart failure (HF) was induced by volume overload achieved by creation of the aorto-caval fistula...

Brain contusions (BCs) are one of the most frequent lesions in patients with moderate and severe traumatic brain injury (TBI). BCs increase their volume due to perilesional edema formation and/or hemorrhagic transformation. This may have deleterious consequences and its mechanisms are still poorly understood. We previously identified de novo upregulation SUR1, the regulatory subunit of KATP and other channels, in human BCs. Our aim here was to study the expression of the pore-forming subunit of KATP, Kir6.2, in human BCs, and identify its localization in different cell types...

Vascular disruption is the underlying cause of cerebral hemorrhage, including intracerebral, subarachnoid and intraventricular hemorrhage. The disease etiology also involves cerebral hemorrhage-induced blood-brain barrier (BBB) disruption, which contributes an important component to brain injury after the initial cerebral hemorrhage. BBB loss drives vasogenic edema, allows leukocyte extravasation and may lead to the entry of potentially neurotoxic and vasoactive compounds into brain. This review summarizes current information on changes in brain endothelial junction proteins in response to cerebral hemorrhage (and clot-related factors), the mechanisms underlying junction modification and potential therapeutic targets to limit BBB disruption and, potentially, hemorrhage occurrence...
